Already in use in London’s National Gallery, LA’s Universal Studios and on Carnival Cruise ships, Triple E’s revolutionary Chainbeam track offers the solid construction of Unibeam together with the amazing flexibility of its chain driven systems.
Chainbeam is the newest member of a family of track systems that share the same external dimensions and principal components, but have their own unique applications in the world of travelling curtains and scenery. The first in the range was Unitrack, used for systems that are regularly demounted or for rental applications, followed by Unibeam, designed specifically for permanent installations. Capable of taking heavier loads, Unibeam is also suitable for use as a multipurpose suspension bar in its own right.
Taking the Unibeam concept one step further, Chainbeam has a dual run of 3/8″ duplex chain running in a UHMW (ultra high molecular weight polyethylene) guide in the lower web of the track profile. Using a laser profiled comb, the chain is attached to the master carrier and the curtains are then attached to standard Unitrack carriers. The track itself takes the weight of the curtains or scenery and the chain drives the load. Combined with absolute encoders, this non-slip system ensures accurate positioning to within +/- 5mm and is ideal for large scenic pieces that have a number of exact stopping positions and are required to line up precisely with projection or lighting effects. Once programmed, Chainbeam will return with absolute accuracy time after time, unlike a wire or regular rope drive, which is subject to stretching. The Chainbeam system has a motor driven sprocket at one end and a tensioning sprocket at the other, the same drive components being used whether the track is straight or curved.
Chainbeam can be used to carry large, heavy house curtains and scenery effects without the need for the traditional helical drum-type hauling system. Ideal for venues where space is at a premium, by eliminating all the parts associated with a hauling system, Chainbeam gives greater long term reliability and performance. It is also more straightforward and quicker to install, reducing both equipment and labour costs.
